unusual facts about Linear pulse-code modulation



7.1 surround sound

Miracast

Miracast allows a portable device or computer to send, securely, up to 1080p HD video and 5.1 surround sound (AAC and AC3 are optional codecs, mandated codec is linear pulse-code modulation — 16 bits 48 kHz 2 channels).

Starting around 1993, with the introduction of Creative Labs' Sound Blaster AWE32 and Gravis' Ultrasound sound cards, the term "wavetable" started to be applied as a marketing term to any sound card that used PCM samples as the basis of sound creation.
